The owner or custodian of a dog, cat, or ferret four months old or
older to be imported into the County for any purpose shall forward
a certificate, issued by a licensed veterinarian, to the Public Health
Veterinarian, within 10 days of the animal's arrival in the County,
that:

The owner or custodian of a dog, cat, or ferret brought into the County for a period of less than 30 days is exempt from the requirement to forward a certificate to the Public Health Veterinarian as specified in Subsection B if a copy of a certificate signed by a licensed veterinarian can be presented to the local Health Officer immediately when requested.

Within 90 days of the dangerous dog declaration, the owner shall
have the animal implanted with a microchip by a licensed veterinarian
for permanent identification and register with the microchip company,
and shall provide the corresponding microchip to the Animal Care and
Control Authority.

An Animal Care and Control Officer shall, upon receipt of permission from the property owner or after obtaining a court-authorized search warrant, enter onto the property where a vicious or dangerous dog is to be confined [as described in § 142-12, Subsection (d)(1)] and check for compliance with the dangerous dog regulations at any reasonable time.

An Animal Care and Control Officer or law enforcement officer may
pursue and destroy an animal at large that is placing the public in
imminent danger or an animal in the act of attacking livestock or
other domestic animals. Refer to § 11-505 of Article 24
of the Annotated Code of Maryland.

An annual dangerous dog registration fee of $75 per dog shall be
assessed for any dog declared dangerous by the Animal Care and Control
Authority. The first dangerous dog registration fee shall be paid
within 10 days of the declaration and annually thereafter. Failure
to pay the annual dangerous dog registration fee shall result in a
fine double the registration fee owed.

The owner of a dangerous dog or potentially dangerous dog who moves
from one residence to another within Cecil County shall inform the
Animal Care and Control Authority in writing of the change of address
within 30 days.
